Install dependencies

Hi, Is the program still work on the devices that are mentioned on the https://alephsecurity.com/2018/01/22/qualcomm-edl-1/ Even with the latest android (9.x) on them?

Can the provide us the installation guide & dependencies to run this program on both linux & windows.

I got the the following error by,

```
$git clone https://github.com/alephsecurity/firehorse
$cd firehorse/host
$firehorse/host(master)# python firehorse.py -t ugglite target read_partition devinfo
INFO: Downloading partition devinfo to ugglite-devinfo-read.bin...

File "/usr/lib/python2.7/subprocess.py", line 1047, in _execute_child
raise child_exception

```

Is there any dependencies needs to be installed inorder to make this work?

I'm trying to unlock the boot loader of the Xiaomi device which uses the `prog_emmc_firehose_8953_ddr.mbn` via EDL mode.

Any help would be appreciative.
